The implementation in of_regulator_match() already ensures match->init_data is
not NULL for all matched cases if the return value of of_regulator_match() > 0.

Thus remove NULL test for rmatch[i].init_data.

This patch also fixes the condition for loop iteration.
The for loop should iterate "matched" times rather than ARRAY_SIZE(regulators)
because we only allocate "matched" number of entries for rdata.
Though in most cases, "matched" == ARRAY_SIZE(regulators).

This patch adds new regulator driver to support max77693 chip's regulators.
max77693 has two linear voltage regulators and one current regulator which
can be controlled through I2C bus. This driver also supports device tree.
